Rows duplication in my query result

Hello Community,

Kindly assist in reviewing this query when I ran it, it resulted in multiple duplication of rows

Select I.INV_ADV_ID AS INVOICE_NO

, (CASE
   WHEN (ADR.ADDR_2_TX = '') THEN
   CONCAT(ADR.ADDR_1_TX, ', ', ADR.CITY_TX, ', ', ADR.STATE_TX, ', ', ADR.POSTAL_CD_TX)
   ELSE
   CONCAT(ADR.ADDR_1_TX, ' ', ADR.ADDR_2_TX, ' ', ADR.CITY_TX, ', ', ADR.STATE_TX, ', ', ADR.POSTAL_CD_TX)
   END) AS SERVICE_ADDR
,ADR.STATE_TX 
, LDC.LDC_ACCT_NO
,LDC.LDC_ACCT_ID


, coalesce(convert(char(10), convert(date, (convert(varchar(8), nullif(MU.SERVICE_PERIOD_BEGIN_DT, 0))), 113)),'') AS SERVICE_PERIOD_BEGIN_DT
, coalesce(convert(char(10), convert(date, (convert(varchar(8), nullif(MU.SERVICE_PERIOD_END_DT, 0))), 113)),'') AS SERVICE_PERIOD_END_DT
, MU.BEGINNING_READING_NO AS PREV_READ
, MU.ENDING_READING_NO AS CURR_READ
, CAST(((MU.ENDING_READING_NO - MU.BEGINNING_READING_NO) * MU.METER_MULTIPLIER_NO) AS DECIMAL (10,0)) AS USAGE
, MU.QTY_DELIVERED_NO
, TH.PRICE_PER_UNIT_NO
, TH.TRANS_AM
, TH.TRANS_QTY
, ug.RATE_CD
